I have a d16z6 with 11psi and it burning oil I took off the turbo. the oil is comming out the head. so i took off the head and got a valve job. put the back on and still burning oil . I'm going to put the z6 head on a6 bottom end what compression would it be and how much boost can i run???

As a daily driver, I'd say it would be safe if you keep it under ~200 whp.

 

I am wondering the same thing, I have a a6 block with a z6 head and i need to know the compression ratio. I am boosting 12psi.
